SPRING-BED.

SPECIFICATION forming part of Letters Patent No. 608,232, dated August2,' 1898; Application led January 26, 1897. Serial No. 620,768. (Nomodel.)`

To all whom zit may concern.-

Beit known that I, NATHANIEL J. SHIELDs, a citizen of the United States,residing at Stevenson, in the county of Morton and State of NorthDakota, have invented certain new and useful Improvements inSpring-Beds;

` and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to spring-beds.

My object is to provide a spring-bed of improved construction which Willcomprise but feur parts, all of which will be of extremely strong andAdurable construction and so ar ranged and disposed in relation to eachother that a very easy bed will be provided.

A further object is the provision of a springbed the parts of which areadjustable in a novel manner and are peculiarly disposed in relation toeach other, so that the resistance to pressure can be :regulated to anydesired degree.

I-Iaving these objects in view, the invention consists of a novel formof spring-bed comprising certain improved features and peculiarcombinations appearing more fully hereinafter.

In the accompanying drawings, Figure lis aplan view of my improvedspring-bed; Fig. 2, an end View thereof, and Fig. 3 a detail View of theconnection of the bed.

There are two side rails l and 2, which are of similar construction.

vThe numerals 3 and 4t designate end rails.

At each corner of the bed there is a bolt 5, having a nut G. Said boltpasses loosely through the side rails, but its shank is received in aslot 7, leading from the end of the end rail inwardly. It will thus beseen that the side rails can be moved outwardly orinwardly and thesebolts clamped in position, so that the proper tension can be brought tobear on the woven-wire bed-bottom now to be described. This Woven-Wirebed-bottom is designated by the numeral 8. Strips 9 and 10 are screwedor nailed to the tops of the side rails. These strips are preferablyprovided with outer rounded edges 1l, so that at one of the corners thebed-bottom will not be damaged in any manner.

The Woven-Wire bed-bottom is stretched crosswise of the frame over thestrips 9 and 10, which are of. sufficient height to raise 'thebed-bottom flush with the end rail and has its edges passed down theside rail and bent thereunder. Clamping strips 10'w and ll' firmly bindthe edges of the bed-bottom to the bottoms of the side rails. It Will be observed that the bed-bottom is connected to the side rails only andnot attached to the end rails in any manner. There is great advantage inthus placing the bed-bottom, as it is then in the best position to adaptitself to the form of the occupant of the bed, and hence be extremelycomfortable. Connected to each end rail are downwardly-extending lugs 12and 13. The numerals 11i and l5 designate adjusting-screws, which passthrough said lugs and bear against the side rails. By turning the screwsthe side rails can be spread, as found desirable. At 16 I haveishown acenterrail, which extends longitudinally of the bed and centrallythereof.

The numerals 17 and 18 designate hanger screw-threaded bolts Which passthrough the end rails and the end portions of the center rail, and eachis provided with a nut 19. By turning these nuts the center rail can beraised or lowered. The numerals 2O and 2l designate braces which arepivotally connected both to the center rail and the side rails. Thesebraces prevent the side rails from springing in when the bed is in use.At 22 there is shown a series of spiral springs which are secured to thecenter rail and support the center portion of the bed-bottom S.

Gwing to the peculiar construction of my improved spring-bed it can beadjusted, as before described, to bring aproper tension both on thebed-bottom and the spiral springs, l

so that the bed will be extremely easy and comfortable.

There are many slight changes which could be resorted to inconstructing'my invention without detracting from any of its advantages,and it is to be understood, therefore, that I do not limit myself to theprecise construction herein shown and described, but

IOO

consider that I am'entitled to all such variations as come Within thespirit and scope of the invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a spring-bed, the combination with a frame composed of side andend rails relatively adjustable, of a flexible bed-bottom connected to'said frame, a center rail extending longitudinally of the bed below thebed` bottom, braces secured to said center' rail and to the side railsof the frame, and lneans for adjusting said center rail vertically,andmaintaining the same in adj usted position whereby the tension of thebed-bottom can be regulated.
